# Typhoon <img align="right" src="https://storage.googleapis.com/poseidon/typhoon-logo.png">
|
||||
|
||||
Typhoon is a minimal and free Kubernetes distribution.
|
||||
|
||||
* Minimal, stable base Kubernetes distribution
|
||||
* Declarative infrastructure and configuration
|
||||
* Free (freedom and cost) and privacy-respecting
|
||||
* Practical for labs, datacenters, and clouds
|
||||
|
||||
Typhoon distributes upstream Kubernetes, architectural conventions, and cluster addons, much like a GNU/Linux distribution provides the Linux kernel and userspace components.
|
||||
|
||||
## Features <a href="https://www.cncf.io/certification/software-conformance/"><img align="right" src="https://storage.googleapis.com/poseidon/certified-kubernetes.png"></a>
|
||||
|
||||
* Kubernetes v1.15.0 (upstream, via [kubernetes-incubator/bootkube](https://github.com/kubernetes-incubator/bootkube))
|
||||
* Single or multi-master, [Calico](https://www.projectcalico.org/) or [flannel](https://github.com/coreos/flannel) networking
|
||||
* On-cluster etcd with TLS, [RBAC](https://kubernetes.io/docs/admin/authorization/rbac/)-enabled, [network policy](https://kubernetes.io/docs/concepts/services-networking/network-policies/)
|
||||
* Advanced features like [worker pools](https://typhoon.psdn.io/advanced/worker-pools/) and [spot](https://typhoon.psdn.io/cl/aws/#spot) workers
|
||||
* Ready for Ingress, Prometheus, Grafana, and other optional [addons](https://typhoon.psdn.io/addons/overview/)

|

Typhoon is a minimal and free Kubernetes distribution.
|
||||
|
||||
* Minimal, stable base Kubernetes distribution
|
||||
* Declarative infrastructure and configuration
|
||||
* Free (freedom and cost) and privacy-respecting
|
||||
* Practical for labs, datacenters, and clouds
|
||||
|
||||
Typhoon distributes upstream Kubernetes, architectural conventions, and cluster addons, much like a GNU/Linux distribution provides the Linux kernel and userspace components.

||||

# Typhoon <img align="right" src="https://storage.googleapis.com/poseidon/typhoon-logo.png">
|
||||
|
||||
Typhoon is a minimal and free Kubernetes distribution.
|
||||
|
||||
* Minimal, stable base Kubernetes distribution
|
||||
* Declarative infrastructure and configuration
|
||||
* Free (freedom and cost) and privacy-respecting
|
||||
* Practical for labs, datacenters, and clouds
|
||||
|
||||
Typhoon distributes upstream Kubernetes, architectural conventions, and cluster addons, much like a GNU/Linux distribution provides the Linux kernel and userspace components.
|
||||
|
||||
## Features <a href="https://www.cncf.io/certification/software-conformance/"><img align="right" src="https://storage.googleapis.com/poseidon/certified-kubernetes.png"></a>
|
||||
|
||||
* Kubernetes v1.15.0 (upstream, via [kubernetes-incubator/bootkube](https://github.com/kubernetes-incubator/bootkube))
|
||||
* Single or multi-master, [flannel](https://github.com/coreos/flannel) networking
|
||||
* On-cluster etcd with TLS, [RBAC](https://kubernetes.io/docs/admin/authorization/rbac/)-enabled
|
||||
* Ready for Ingress, Prometheus, Grafana, and other optional [addons](https://typhoon.psdn.io/addons/overview/)

# Typhoon <img align="right" src="https://storage.googleapis.com/poseidon/typhoon-logo.png">
|
||||
|
||||
Typhoon is a minimal and free Kubernetes distribution.
|
||||
|
||||
* Minimal, stable base Kubernetes distribution
|
||||
* Declarative infrastructure and configuration
|
||||
* Free (freedom and cost) and privacy-respecting
|
||||
* Practical for labs, datacenters, and clouds
|
||||
|
||||
Typhoon distributes upstream Kubernetes, architectural conventions, and cluster addons, much like a GNU/Linux distribution provides the Linux kernel and userspace components.
|
||||
|
||||
## Features <a href="https://www.cncf.io/certification/software-conformance/"><img align="right" src="https://storage.googleapis.com/poseidon/certified-kubernetes.png"></a>
|
||||
|
||||
* Kubernetes v1.15.0 (upstream, via [kubernetes-incubator/bootkube](https://github.com/kubernetes-incubator/bootkube))
|
||||
* Single or multi-master, [Calico](https://www.projectcalico.org/) or [flannel](https://github.com/coreos/flannel) networking
|
||||
* On-cluster etcd with TLS, [RBAC](https://kubernetes.io/docs/admin/authorization/rbac/)-enabled, [network policy](https://kubernetes.io/docs/concepts/services-networking/network-policies/)
|
||||
* Advanced features like [worker pools](https://typhoon.psdn.io/advanced/worker-pools/) and [preemptible](https://typhoon.psdn.io/cl/google-cloud/#preemption) workers
|
||||
* Ready for Ingress, Prometheus, Grafana, and other optional [addons](https://typhoon.psdn.io/addons/overview/)
|
||||
